标准范围

ISO 25761:2008中规定的方法测量可溶于冰醋酸并与高氯酸反应的多元醇中的基本成分。用该方法对含氮0.3%至10%的样品进行了评估。该方法适用于用于聚氨酯反应的聚醚多元醇和聚醚多元醇混合物。结果是批次间均匀性的度量，可用于评估聚氨酯反应中的反应性。

The method specified in ISO 25761:2008 measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures of batch-to-batch uniformity and may be used to estimate reactivity in polyurethane reactions.
